Betting analysis — odds conversion, de-vigging, edge detection, Kelly criterion, arbitrage detection, parlay analysis, and line movement. Pure computation, no API calls. Works with odds from any source: ESPN (American odds), Polymarket (decimal probabilities), Kalshi (integer probabilities). Use when: user asks about bet sizing, expected value, edge analysis, Kelly criterion, arbitrage, hedging, profit locking, weighted outcome coverage, parlays, line movement, odds conversion, or comparing odds across sources. Also use when you have odds from ESPN and a prediction market price and want to evaluate whether a bet has positive expected value. Don't use when: user asks for live odds or market data — use polymarket, kalshi, or the sport-specific skill to fetch odds first, then use this skill to analyze them.

Use when Codex is acting as an autonomous World Cup betting operator in wordcup-space: choosing weekly matches, reading Betway odds from Chrome/screenshots, deciding markets/stakes/parlays, hedging open slips, creating intents, recording slips, settling, or reviewing historical betting performance.

Use when operating this repository as a Codex-powered World Cup prediction, betting-analysis, bankroll, odds-capture, bet-slip, settlement, or review workspace. This is the umbrella skill for third-party Codex users after cloning the repo.

Use when Codex predicts World Cup match scores in wordcup-space, especially weekly pre-match score forecasts, recording predictions through /api/predictions, checking final results, or reviewing prediction accuracy. This is separate from betting decisions.
